Or not: https://github.com/Kunzisoft/KeePassDX/issues/2321
They are imo clearly gearing up to lock down passkeys in practice one day so that you will only be able to use those tied to a Google or Apple account (or some new player). They're already threatening in these issues to blacklist open implementations that don't submit to their requirements, and then requiring an attested client would then become the "best practice" adopted blindly and widely. I think the only hope is for the open clients to fully submit, hoping to avoid full attestation, while not making it too hard to patch out the anti-features. Of course, anyone who can't compile is screwed though.
...and it characteristic the level of patronising arrogance in the issue thread
"This is normal. It is not recommended to copy passwords to the clipboard in any case, this mitigates this behavior and complies with new Web Authentication standards."
This does not even invite a discussion. Maybe some people run tight, safe systems and know what they are doing? Maybe some people never rely on a single password being the only thing between them an an account compromise? Nope. Some patronising guy knows it all, and will override what people want to do on their machines.
... have you heard of passkeys?
Yes, it's as stupid as it sounds. And works about as well.
